[all variants] virtual box will not start in /etc/rc.local

My /etc/rc.local file has
VBoxManage startvm fedora-18-lxde --type headless
exit 0

at the end. my server has to gui and I have to ssh in issue the command "VBoxManage startvm fedora-18-lxde --type headless" just to run this virtual server. I thought that by putting the command in /etc/rc.local it would startup when the server does each time the server is restarted
